<title>Description</title>
<para><command>systemd-detect-virt</command> detects
execution in a virtualized environment. It identifies
the virtualization technology and can distuingish full
VM virtualization from container
virtualization.</para>
<para>When executed without <option>--quiet</option>
will print a short identifier for the detected
virtualization technology. The following technologies
are currently identified: <varname>qemu</varname>,
<varname>kvm</varname>, <varname>vmware</varname>,
<varname>microsoft</varname>,
<varname>oracle</varname>, <varname>xen</varname>,
<varname>bochs</varname>, <varname>chroot</varname>,
<varname>openvz</varname>, <varname>lxc</varname>,
<varname>lxc-libvirt</varname>,
<varname>systemd-nspawn</varname>.</para>
<para>If multiple virtualization solutions are used
only the "innermost" is detected and identified. That
means if both VM virtualization and container
virtualization are used in conjunction only the latter
will be identified (unless <option>--vm</option> is
passed).</para>
